There are a lot of ambiguities about the environment of the company Floral Direct in the given assignment description. It is unclear how many clients use Floral Direct and how many companies fulfill these orders. In our model, we are mainly focusing on the market in the Netherlands.\\
\\
Given the relatively short bidding time of 30 minutes that companies have and the fact that flowers are preferably delivered within a short range of the local companies, we initially expected that Floral Direct would have over 1000 associated local companies. To fulfill this demand, we thought that Floral Direct will have about ten thousand orders per day. \\
\\
In The Netherlands, we spend \euro 1.1 billion on flowers and plants. With 5365 flower stores in The Netherlands, the average turnover per store is about \euro $205$ thousand. The average spending per customer is about \euro30-\euro35. On a yearly basis, this brings us to $31,428,571$ orders. We assume 25\% of these orders are done via the internet. This means $7,857,143$ orders per year over the internet.\\
\\
In The Netherlands, we have 3 big online flower stores. One of them is much better graded than the other two, with an appropriately big conversion. We assume we have 40\% market share, so we have 40\% of the flower stores in our chain, which is 2146 stores. We also have 40\% of the online orders through our website, which is $7,857,143*40\%=3,142,857$ orders per year, so $3,142,857/365=8610$ orders per day.
